Learn How to Win Material: Discovered Attack
This chess endgame puzzle is a classic example of a discovered attack in a long middlegame-to-endgame transition. One piece is forced to move or be exchanged, and that action opens a line for a hidden attacker to strike with tempo. The result is a decisive material gain rather than a mating finish. In classical chess, these motifs often appear when rooks and bishops coordinate against an exposed king and loose pieces.
